I think I understand what the op means. It means we paid 100 bucks for a shoddy/lazy software port.
It's always best to have code run natively- it will just be a better, smoother app, period. Witt that said, having two distinct code bases is a pain in the arse for devs. Someone's going to get the short end of the stick here, and sadly it's us Mac folk.
However to the op- chances are most n the forum are only tech guys as far as camera goes so eh don't really have a clue to what the negatives could be. So in this forum, the argument is a wash, unfortunately.
Lazy port? So you are paying only for the port not the developing of the algorithms to make it work? And how you know it is lazy? How many hours took him?
"Lazy" all depends if the dev went for the easiest option at the expense of how well the app runs in the mac environment. Im not saying either or, thats on them- but native will ALWAYS be better, regardless of any circumstances.
Personally, Im always curious about visual related software not appearing on macs first- osx is still the lead content creation platform for most creatives. Photography, i would think, falls under that realm.
In recent years a lot of the advantages are falling by the wayside or being equalized. First, basically all Adobe software runs on Windows as well. Second, Final Cut X cause huge disruptions for many people, and they either have not upgraded, or had needed features that hadn't yet been implemented (or weren't going to be), and so they either stuck with the previous version, or jumped ship to Avid which can run on Windows. Third, the Mac Pro's have gone to a somewhat longer refresh cycle, while the big OEMs which you can get machines certified for certain applications have kept up with the new hardware which gives drastically more processing power for similar price, or better value for similar power at generally lower prices. Last, especially with Windows 7 and beyond, many of the big issues such as font handling and rendering are catching up with Apple in many ways, and so Mac no longer has the bigger on-screen rendering advantages that they used to.
A lot of people (from what I've heard) has said Apple seems to be focusing on their iOS devices and the AppStore/iTunes, and paying less and less attention to the Pro users that do serious content creation. After all, it may be high margin, but there are a LOT more users for iOS devices out there and I'm sure they have good margins there despite it being the consumer space, rather than the pro space.
